New faculty appointments Urs Wiedemann, nuclear theory. Urs’s main research is on the theory of dense QCD matter now being studied in relativistic heavy ion collisions at RHIC at nearby Brookhaven National Laboratory (BNL – co managed by Stony Brook University and Battelle Memorial Institute) and after about 2007 at the LHC at CERN. Fresh from a staff theory position at CERN, Urs joined us as Assistant Professor in January 2006 in a joint position with the RIKEN Institute at BNL. RHIC at BNL LHC at CERN New faculty appointments Leonardo Rastelli, foundations of string field theory. After a postdoc at Princeton University, Leonardo joined us as Assistant Professor in the Yang Institute for Theoretical Physics in January 2006. General lessons for open/closed duality from non-critical strings Abstract for July, 2004 lecture at Prospects in Theoretical Physics meeting held at Institute for Advanced Study, Princeton: How does open/closed duality work? In some non- critical (often topological) string theories we can answer this question exactly. We begin by reviewing the relevant geometry of the moduli space of open and closed Riemann surfaces. We then describe some simplex matrix models and their precise interpretation as the open string duals to topological closed string theories. We attempt to draw general lessons about AdS/CFT.* *I had to look it up: AdS = anti de Sitter space; CFT = conformal field theory. AdS/CFT refers a correspondence proposed by Maldacena in 1997 that has been very influential. Faculty recently arrived (and hard at work) Adam Durst, condensed matter theory. Adam studies high Tc superconductors, 2- dimensional electron gases. After a postdoc at Yale, Adam joined us as Assistant Professor in January 2005.

Yang Institute for Theoretical Physics Thursday and Friday, 20-21 October On Friday 21 October at 4:30 pm (SAC Auditorium) a Sir Run Run Shaw and Provost’s Lecture by John Stachel, Center for Einstein Studies, Boston University Einstein’s Odyssey: From Special to General Relativity Simons Lecturers The bequest by the Simons Foundation is being used again this year to sponsor two special lecturers to visit the department for about a week and give a combination of colloquium and seminar-level talks. Each lecturer is available for discussions and interactions with students and faculty. Uzi Landman of Georgia Tech is an expert on science at the nanoscale. His 25 October Simons lecture was Small is Different: Emergent Physics and Chemistry in the Nonscalable Regime. Frank Wilczek of MIT shared the 2004 Nobel Prize in Physics for co-discovery of asymptotic freedom in the strong force. He will visit and lecture in April. Research highlights of our community of researchers To give students a flavor for the research opportunities that the Department offers, I asked each research area to prepare summary slides. Disclaimer: Any errors in presentation/description are mine. I attempt to organize them from largest to smallest, but even this has problems! Phys/Astro merger Physics and Astronomy + YITP research expenditures ~ 13.9M$ in FY ‘05 (highest in the university, ¼ of total for College of Arts and Sciences) Extragalactic Astronomy and Cosmology A. Evans, K. M. Lanzetta, P. Solomon, & A. Yahil Galaxy Formation and Evolution • Graduate student S. Gromoll and K. Lanzetta have developed a method of measuring faint galaxies in low spatial resolution images at thermal infrared wavelengths (3.5 – 24 μ) obtained by the new Spitzer Space Telescope • The method uses high spatial resolution images at optical and near-infrared wavelengths obtained by the Hubble Space Telescope as “spatial templates.” • These measurements are being used to determine the rest-frame near-infrared luminosities of galaxies of redshift z = 0 – 10, from which the comoving mass density of stars in galaxies versus cosmic epoch can be determined. This can directly establish the epoch and time scale of galaxy formation. Liquid-Mirror Telescope Development K. M. Lanzetta & G. Sprouse Large Zenith Telescope (LZT) prototype • 6 m diameter liquid-mirror telescope near Vancouver, British Columbia • Optical-quality mylar cover built and installed to improve accuracy of liquid Hg surface • Telescope has achieved near- seeing-limited performance Advance Liquid Patrol for Asteroids, Cosmology, and Astrophysics (ALPACA) • Successful external review (R. Williams, J. Beckers, L. Seppala) of conceptual design of ALPACA held on July 15, 2005 • Choice of site narrowed to two possibilities at the Cerro Tololo Inter-American Observatory in northern Chile • Site testing equipment (microthermal sensor array and lunar scintillometer) built and about to be installed Takai (BNL/Adjunct), Marx, NSF has supplied initial funding. Forman, Rijssenbeek MARIACHI – a new way to search for Ultra High Energy Cosmic Rays (UHECR) E > 1018 eV A few dozen have been seen by ground arrays looking at either shower debris or atmospheric fluorescence. UHECR are too energetic to originate in our galaxy or nearby galaxies. UHECR are too energetic to propagate through the microwave background from distant sources. Cosmic rays initiate showers when they collide with the atmosphere. Radio waves from distant sources (i.e. TV) may be reflected by the ionization created by the shower particles. This technique is already used to study micrometeors (Radio Meteor Scatter) higher in the atmosphere. To confirm that an observed signal originates from UHECR we need to independently observe shower debris – will do this with simple counters18 built, installed, and operated by local high school teachers and students.• Diffraction microscopy (ALS) • Xiaojing Huang, Enju Lima, Huijie Miao, David Shapiro (PhD December 2004), Jan Steinbrener, plus Aaron Neiman (Biology), Andrew Stewart, David Sayre, Chris Jacobsen, and Janos Kirz (ALS acting director) • Imaging beyond resolution limit of x-ray lenses: collect far-field diffraction pattern and use iterative algorithms to find phase consistent with finite-sized object.
